***GCT Semiconductor Announces Qualification of Bluetooth Radio
and Baseband Processor
(February 5)

GCT Semiconductor Inc.-- a fabless semiconductor firm and
associate member of the Bluetooth SIG -- on Tuesday announced the
qualification of its GDM1000 Bluetooth radio and GDM1201
Bluetooth baseband processor in compliance with the Bluetooth
specification version 1.1.

Both devices are fabricated on standard CMOS and designed for use
in high-performance, cost-effective Bluetooth systems.

The GDM1000 is a fully integrated Bluetooth radio transceiver
with GFSK modem. The radio design is based on GCT's proprietary
direct conversion architecture, which GCT claims offers high
receiver linearity and exceptional blocking performance, to
promote robust operation in the crowded 2.4GHz ISM band.

The IC is fabricated with RF CMOS technology, which provides low-
cost RF solutions to enable communications via Bluetooth or other
wireless standards.

The GDM1000 is designed for Class II/III Bluetooth systems, using
a minimum number of external components. It also supports Class I
Bluetooth applications through the addition of an external power
amplifier.

The GDM1000 provides all of the signal and logic interfaces to
complement a Bluetooth baseband device, such as GCT's GDM1201
Baseband IC, to build a complete low-cost, fully functional
Bluetooth solution.

The GDM1201 is a baseband controller providing Bluetooth
functionality for high data rate, short distance wireless
communication in the 2.4GHz ISM band. Coupled with the GDM1000
and external flash memory, it provides a fully compliant
Bluetooth solution for data and voice communication.

The on-chip 32-bit microcontroller supports the highest data
rates currently seen in Bluetooth applications. The baseband
architecture is based upon GCT's proprietary 64 MIPS PiCOII-RISC
embedded processor for low power processing and includes
sufficient SRAM (64 KB) to support the on-chip Bluetooth software
stack.

The programmable IC supports multiple-standard interfaces, such
as BlueRF RXMODE2/3 uni-bi-directional, and JTAG serial
interface, providing customers with outstanding interface
flexibility. Additionally, the chip supports standard UART, USB
with host and device combo functions and integrates a 16 bit
Sigma-Delta PCM/CVSD audio codec.

Sampling for the GDM1000 and GDM1201 will be available to a
select group of prospective customers in April 2002.
